What Is a Gutenberg Blocks Plugin?

A Gutenberg blocks plugin adds new blocks to the WordPress block editor. The default editor gives you basic blocks like paragraphs, headings, and images. A blocks plugin adds advanced ones like sliders, pricing tables, post grids, accordions, and forms.

There are two kinds:

1. Block library plugins add many blocks at once (like Spectra or Essential Blocks).
2. Single-purpose block plugins focus on one job, like post grids or testimonials (like The Post Grid).
